According to The Health, among the factors affecting male fertility, smoking is a clear and long-term cause of harm.
Nicotine and thousands of toxic chemicals in cigarette smoke reduce blood flow to the testicles, destroy sperm-producing cells and change DNA. As a result, sperm count is dropped sharply, quality is impaired, mobility is poor, and the rate of deformed sperm increases.
Not only that, cigarettes also reduce testosterone levels - a hormone important for reproductive health. This is the reason why smoking is often accompanied by helplessness, decreased desire and pregnancy failure.
In addition to smoking, other factors also contribute to sperm decline such as:
Warm bath: Warm bath can help the body relax, but can also reduce sperm count due to increased testicular temperature. This can damage sperm quality and quantity.
Carry tight pants: Wearing pants that are too tight can increase the temperature of your testicles. This can reduce both sperm count and quality.
Mobile phone vibration: Mobile phone vibration has a big impact on sperm production. According to one study, mobile phone radiation is very harmful to the body, not excluding the reduction of sperm count.
